Abstract

Die Erfindung betrifft eine Vorrichtung zur Lageregelung eines berührungslos gelagerten schnelldrehenden Rotors, insbesondere eines Spinnrotors, die eine Sensoreinrichtung zur fortlaufenden Erzeugung von Rotorlagesignalen und eine die Rotorlagesignale verarbeitende Steuereinrichtung (6) besitzt, wobei die Steuereinrichtung (6) fortlaufend eine Stellgröße an eine die Rotorlage beeinflussende Aktoreinrichtung ausgibt. Die Steuereinrichtung (6) ist so eingerichtet, daß die Steigung des Kurvenverlaufes eines weiteren Signals, aus dem die Stellgröße hergeleitet wird, auf einen maximalen Betrag begrenzt ist und bei Auftreten von höheren Schwingungsfrequenzen der Rotorlagesignale eine Absenkung der Schwingungsamplituden des weiteren Signals für die Aktoreinrichtung bei gleichzeitig kleinem Phasenfehler bewirkbar ist. Mit der erfindungsgemäßen Vorrichtung läßt sich auf einfache Weise ein geringer Energieverbrauch, eine erweiterte Aussteuerbarkeit und eine höhere Betriebssicherheit erreichen.The invention relates to a device for position control a contactless fast rotating rotor, in particular a spinning rotor, which is a sensor device for the continuous generation of rotor position signals and a the rotor position signal processing control device (6) has, wherein the control device (6) continuously a Manipulated variable to a rotor position influencing Actuator outputs. The control device (6) is so set up that the slope of the curve of a another signal from which the manipulated variable is derived is limited to a maximum amount and on occurrence of higher vibration frequencies of the rotor position signals a Reduction of the oscillation amplitudes of the further signal for the actuator device at the same time small phase error is feasible. With the device according to the invention leaves easily a low energy consumption, a extended modulation and higher Achieve operational reliability.

Die erfindungsgemäße Vorrichtung ist vorteilhaft bei einem magnetisch gelagerten Spinnrotor (1) einsetzbar.
